/**//**
 *tiannet添加了时间选择功能、select,object标签隐藏功能，还有其它小功能。
 *使用方法：
 * (1)只选择日期 <input type="text" name="date" readOnly onClick="setDay(this);">
 * (2)选择日期和小时 <input type="text" name="dateh" readOnly onClick="setDayH(this);">
 * (3)选择日期和小时及分钟 <input type="text" name="datehm" readOnly onClick="setDayHM(this);">
 *设置参数的方法
 * (1)设置日期分隔符 setDateSplit(strSplit);默认为"-"
 * (2)设置日期与时间之间的分隔符 setDateTimeSplit(strSplit);默认为" "
 * (3)设置时间分隔符 setTimeSplit(strSplit);默认为":"
 * (4)设置(1),(2),(3)中的分隔符 setSplit(strDateSplit,strDateTimeSplit,strTimeSplit);
 * (5)设置开始和结束年份 setYearPeriod(intDateBeg,intDateEnd)
 *说明：
 * 默认返回的日期时间格式如同：2005-02-02 08:08
